What kind of luck are you guys having reloading for the 7 PRC? What powder and bullets are you guys having the best luck with and what velocities are you getting? I am running a 26” barrel with a suppressor and I’m seeing 2850 with 1 moa in accuracy with factory Hornady 175 ELD-Xs.

7mm PRC
Anyone loading lighter projectiles for deer? 175 gr seems a bit heavy. Thinking more in the 139-147 range? Trying to justify using my new rifle for deer season this Fall. I noticed that Hornady has published 7PRC load data for a 139gr CX.

Just for clarity, are you indirectly saying you think this is good or bad, so you want to study alternatives to improve?
Speed or target performance, or both?
Just for perspective, your 175 @ 2850 is giving you 4280 Joules or 3157 ft*lbs
To get this to 3000 fps you would need an additional 341 ft*lbs worth of energy, which is like adding the equivalent of a 9mm to the load.
There was lots of hype and marketing when the 7 PRC was released, and after a while there were many folks who thought they should get higher speeds with their 180s too.
If your rig is getting 2850 and an honest 1 MOA, that is better than the average that I have seen. Not telling you to settle, but for perspective many folks in marketing are known to say things that they know are not true.
To get this up to speed (62KSI) you will need to increase the charge with handloads, or find some of the factory loads where they already did this. There was some ammo at first that was fast and later some that was slower, and recently it is getting faster again. YMMV
Am getting 2900 out of a 26” barrel with 65.1 of N655 with 180 Berger’s. I’d actually like to be at 2850 for my purpose which is just target shooting at longer distances (1200-1500 yds)
Man, it’s hard to believe nobody replied to that. I’m in the same boat. I just purchased a brand new one today and kind of curious as to what the normal is on bullet weight and powder.
As mentioned above, the 7prc has its own thread for load data.
The only one I found was a bunch of guys cussing and discussion the seven PRC and how the 6.5 necked up to 7 mm is better or a 300 PRC neck down to 7 mm is better blah blah. Not yet talk about some wildcats that are copycats or some such. I’ll get to stumble across very many loads in that 15 pages, but I’m not reading all of them I’d like to see some actual load data Sierra 160 HPBT to be exact.
I felt the same way when I went to the “7 PRC thread” no real info on my particular component choices and when I posted a question no one replied and no one has.
Start your own thread asking your specific questions. You’ll get these search nazis talking about existing threads but as long as moderators don’t have an issue with it then they can fuck straight off.
I started one yesterday about a new 7mm prc I bought and posted pics of targets just horsing around today. ZERO reply's LOL oh well not going to loose any sleep over it
That’s what I drug home from the store yesterday that shot that factory ammo so good. I don’t even have the barrel broken yet. It’s already throwing .3 MOA groups at 200. I’d like to say it was my handloads, but it wasn’t it was factory ammo how embarrassing. Verdict is still out on that stock. It’s OK I guess I don’t like the color.

This is a load that TxLite shared and it works in my 18 “ 7 prc
73.5 n570 Berger 180 18” carbon barrel 2850
I was using re26 in my 7 prc’s but n570 is the speed king even with a 18” barrel and very easy to tune a load. Obviously work up to that charge weight

All i have is 3 lbs of 7977 and 3 of 8133 I hate to start something and run out. H1000 is everywhere here so I started with a pound of that and an assortment of 160ish bullets. all my little guns shoot RL16 and H4350. Wished the 7PRC did I got tons of that. maybe I could swap my 7977 and 8133 for some RL26 or something
